  1. Health effects resulting from nitrogen dioxide exposure in an indoor ice arena.

    Article - En anglais

    We investigated an outbreak of acute respiratory illness among adolescent ice-hockey players in an indoor ice arena in Stockholm that had a propane-powered ice-resurfacing machine.

    We administered questionnaires to all players, as well as to a reference group that had played ice hockey in indoor arenas with electric ice-resurfacing machines.

    In the exposed group, 55 subjects (55.6%) experienced acute respiratory symptoms, compared with 4 (7.1%) in the reference group (relative risk=7.8 ; 95% confidence interval=3.0,20.3).

    The risk for pulmonary symptoms increased as time spent on the ice increased.

    Levels of nitrogen dioxide up to 2 358 mug/m3 (1 250 ppb) were detected during simulated conditions of the incident.

    The most likely cause of the outbreak was the high level of nitrogen dioxide that resulted from poor ventilation and a malfunctioning ice-resurfacing machine.

    Propane-fueled ice-resurfacing machines should not be used in indoor ice arenas.
